DAVID H. HARNLY, 01E AUSTIN, ILLINOIS.

ADJUSTABLE WIN DOW-SHADE.

Application filed February 2, 1912.

To all whom it may concern;

lie it known that 1, DAVID ll. HARNLY, a citizen of the United States,and resident of Austin, county of Cook, and State of illinois, haveinvented certain new and useful Improvements in r'idjustable lVindow-Shades, of which the following is a specification, and which areillustrated in the companying drawings, forming a part thereof.

The invention relates to window shades which are carried by verticallyadjustable supports, and appertains particularly to the pulley bracketsfor carrying the supports, the guide rods upon which the supports runand to means for equalizing the cords or chains by which the supportsare suspended; the object of the invention being to provide a cheap yetstrong and serviceable bracket, simple means for securing the guide rodsand an efficient equalizing device for the cords or chains.

The invention is fully scribed and is illustraed in ing drawings, inwhich- Figure 1 is a detail perspective elevation of a window with theshade applied thereto; Fig. 2 is a perspective of one of the brackets;Fig. 3 is a perspective of the companion bracket; Figs. 4 and 5 areblanks respectively of the two brackets; and Fig. 6 is a detail of thecord equalizing device.

The window frame is shown at 10 and the shade at 11. This shade iscarried by a pair of supporting members 12, 18 here shown as in the formof plates which are suspended respectively by chains 14, 15 running onsuitable rollers journaled in brackets 16, 17 which are secured to theupper ends of the stiles of the window frame; the chains 14, 15extending down at one side of the window and being attached to a cord orchain 18 which may be engaged with a hook 19 set in the frame stile forthe purpose of se curing the shade in its adjusted positions. Thesupporting elements 12, 13 are guided by rods 20, 21 extendingvertically along the faces of the frame stiles. The suppor ing brackets16, 17 are substantially alike except that they are made to fit oppositesides of the window frame and one 01 them carries a single roller whilethe other is pro vided with a pair of rollers, one of the chains, as 15,being carried across the top of the window frame.

hereinafter dethe accompany- Specification of Letters Patent.

Patented Nov. 19, 1912.

Serial No. 674,944.

The brackets 16, 17 are of sheet metal and are formed up from blanksshown in Figs. 4t and Each bracket comprises a side plate 22 or and anend plate 23, both of these plates having screw holes either or both ofthe plates taking a bearing against the window frame and being securedthereto by means oi screws. The sole 24 oi the bracketis formed byfolding the blank along the dotted line 25 to bring it perpendicular tothe wall plate 22 or The outer end of the sole plate 24 is bentdownwardly on the dotted line 26. The outer end portion 27 of the sidewall plate 22 is bent on the dotted line 28 to fold it under the soleslate thus bringing it parallel with the depending end portion 29 of thesole plate. The parallel lugs 27, 29 thus formed are apertured in lineas shown at 80, 31 to receive the arbor of the rollers 32, 33 over whichthe chains 14, 15 run, these rollers being spaced apart by an annulardisk 34:.

in the case of the bracket 17 the side wall plate 35 is somewhat longerthan the corresponding wall plate 22 of the bracket 16, thus bringingthe parallel lugs 2. 29 closer together as but a single roller 36 isemployed.

The end wall plate 23 of each bracket is cut so as to permit the turningdown to horizontal position of a lip 37 which is apertured as shown at38 to receive the upper end of the rod 20 or 21. The lower ends of theserods are attached to the stiles of the window frame, as shown at 39, 40,each being bent or looped to form a screw eye.

The depending ends of the chains 1 15 are attached to an equalizing loop41 con sisting 01 a short nictal strap, there being used for thispurpose metal which is pliant, being non-elastic. The pull cord 18 isattached to the loop 41, preferably by means of a yoke, the loop passingthrough the yoke. It is important that the chains 14, 15 be easilyadjusted as to length and that the adjustment be maintained. The use ofa pliant metallic strap for forming the equal izing loop provides forthis case of adjustment by merely bending the metal to form the bow forreceiving the roller of the attaching yoke,as in ay be required toproperly proportion the length 01'? the two chains. The metal strap,however, will retain the form given iteven though considerable moreresistance may be developed by friction at one end of the shade than atthe other.

lVhile ordinarily the brackets 16, 17 will be mounted with their wallplate 22 or 35 bearing against the face of the frame stile they may, ifdesired, be so placed that their opposite sides are adjacent the face ofthe stile, longer screws being used to pass through the wall plates. Theapertures 38 in the lugs 37 are located midway between the sides of thebrackets to permit this re-' Yersal of position without Varying thedistance of the rods 20, 21 from the face of the stile frame.

I claim as my invention 1. In an adjustable window shade, thecombination with a shade, supports for the shade and carrying cables, ofbrackets for attachment to a window casing each bracket having a soleplate, end and side wall plates, a pair of parallel lugs depending fromthe sole plate and a cable-carrying roller journaled between the lugs;and guide rods for engaging the supports, the upper end of each guiderod projecting loosely into an aperture in one of the brackets.

2. In an adjustable window shade, the combination with a shade, supportsfor the shade and carrying cables; of brackets for attachment to awindow casing each bracket being formed of sheet metal folded to form asole plate, a wall plate and a pair of parallel lugs depending from thesole plate, a cable-carrying roller journaled between the lugs of eachbracket, and guide rods for engaging the supports, the upper end of eachrod projecting loosely into an aperture in one of the brackets.

3. In an adjustable window shade, the combination with a shade, supportsfor the shade and carrying cables, of brackets for attachment to awindow casing each bracket having a sole plate and a wall plate and apair of parallel lugs depending from the sole plate, a cable-carryingroller journaled between the lugs of each bracket, and guide rods forengaging the supports, the upper end of each rod projecting loosely intoan aperture in one of the brackets.

4. In an adjustable window shade, the combination with a shade, supportsfor the shade and carrying cables, of brackets for attachment to awindow casing each bracket having a sole plate, a wall plate, a pair ofparallel lugs depending from the sole plate and an apertured lipinstanding from the wall plate, a cable-carrying roller journaledbetween the lugs of each bracket, and guide rods for engaging thesupports, the upper end of each rod projecting into the aperture of theinstanding lip of one of the brackets.

In an adjustable window shade, the combination with a shade, supportstor the shade and carrying cables, of brackets for attachment to awindow casin each bracket having a sole plate and a wall plate and apair of parallel lugs depending from the sole plate, a cable-carryingroller ournaled between the lugs of one of the brackets and a pair ofsuch rollers journaled between the lugs of the other bracket, and guiderods for engaging the supports, the upper end of each rod projectingloosely into an aperture in one of the brackets.

6. In an adjustable window shade, in combination, a shade, a pair ofsupports for the shade, a pair of brackets adapted to be attached to theupper end of a window casing, one of such brackets carrying a singleroller and the other of such brackets carrying two rollers, cables forcarrying the supports and running over the rollers, the ends of thecables depending at the same side of the casing, an equalizing loopuniting the depending ends of the cables and being formed of a ribbon ofpliant metal and a pull cord looped onto the equalizing loop.
